Plot was fairly thin, which is how I like my comedies (personally I think Zucker Bros. films that just stuff gags in every scene are the best way to go) but the characters had a lot of charm and depth to them. Sometimes the music bothered me as it was passable and funny, but it wasn't good enough that I'd buy Aldous Snow built a career on it. Then again, Nickelback has, and Snow is better than they are.
Overall, I laughed a lot so it was a good comedy. Rub those furry walls. Drug references ahoy.
Edit: Then again, this song isn't too bad.
